When using the "Q" table in HO 249 which is useable for ten years, remember to apply the "precession and nutations" corrections too. This is not necessary when using the "Q" table in the Air Almanac as that table is based on the current position of Polaris. See my prior post at: http://www.fer3.com/arc/m2.aspx?i=109313 |
